I finally bite the bullet and upgrade to CVS slime from slime-2.0 but it is not a smooth ride. I ended up spending hours reverting changes to my development environment after I discovered that slime-inspector is broken in lispworks. So at least I want to file a report here in case any lispworks user considering to upgrade to the latest and greatest. I typed these in the slime-repl (defstruct rect x y) (defparameter *rect* (make-rect :x 1 :y 2)) M-x slime-inspect *rect* and it will send emacs/lispworks into infinitely loop. Lispworks and emacs both freeze and I don't know how to debug it. This happens in both the windows and linux version of lispworks 5.0.2. I haven't tracked slime development closely but comparing the defpackage form between slime-2.0 and slime-cvs I noticed the following new symbols are exported

"*DEBUG-ON-SWANK-ERROR*" "*DONT-CLOSE*" "*INSPECTOR-DWIM-LOOKUP-HOOKS*" < "CREATE-SWANK-SERVER" "INSPECT-FOR-EMACS" "INSPECT-IN-EMACS" "INSPECT-SLOT-FOR-EMACS" "RUN-AFTER-INIT-HOOK"

so I'm suspecting that the INSPECT-* code might cause this problem, but it is a wild guess. If you want me to provide any more details please let me know. Thanks, -- mac
